The newest member of the MIPI® PHY family, the C-PHYSM, arrived in October 2014 to a mixture of excitement and apprehension. How would this new C-PHY compare to the MIPI D-PHYSM and M-PHY®? What would differentiate the C-PHY, and would it be compatible enough with the D-PHY so that both could coexist in a hybrid subsystem?

Turning Cars Into Mobile Devices: MIPI
Everyone remembers their first car – how you could go where you wanted to go, moving faster and going longer distances – you were mobile. Yes, our cars made us mobile, but today’s cars are becoming mobile devices themselves. More than a means of transportation, cars are evolving into complete mobile devices – connecting and connected to the internet, transportation grids, and to each other. MIPI specifications are playing an important role in this transformation just as they have played the key role in unifying the interfaces in the most common mobile device of all – the smartphone.

With the proliferation of the mobile platform, the accelerating adoption of MIPI® beyond the traditional mobile platform and into safety related applications, testability of MIPI® PHY is becoming a key requirement. While the D-PHY is the MIPI PHY with the widest adoption in the industry today, the RX+ is a D-PHY receiver configuration optimized for full-speed production testing. The presentation will cover an overview of testability challenges in safety related applications, examine the advantages of the RX+ configuration, and compare this configuration to traditionally used D-PHY configurations.

The MIPI Alliance was created in 2003 to benefit the entire mobile industry by establishing standards for hardware and software interfaces in mobile devices.one critical component of mobile device is the physical layer(PHY).The first PHY specification that the MIPI Alliance released in 2009 was the D-PHY.The D-PHY currently operates up to 1Gbps and support both camera serial interface (CSI-2) and display serial interface (DSI), which are increasingly used in both feature and smart phones…..

The curtain is up and the M-PHY specification is taking center stage, positioned handle the many different roles required for a faster, more reliable, physical interface layer (PHY Layer) on mobile devices.

The script for the M-PHY specification was written inside the MIPI (Mobile Industry Processor Interface) Alliance by a working group made up of member companies, and set up to expand the capabilities of mobile devices by defining interface standards that will revolutionize the capabilities of the coming generations of mobile products. Faced with an explosion of mobile multimedia devices…..
